Abstract:
New wireless networks can perform enhanced beamforming training for a multiple access technique, such as orthogonal frequency division multiple-access (OFDMA). The configurations of the stations and the networks presented herein provide a multiple-station beam refinement protocol (MSBRP) that may be used to train the transmit end and/or the receive end for the stations in a dense wireless local area network (WLAN). The MSBRP can have at least two phases. The first phase concurrently trains the receive side of multiple responder stations from one set of training signals sent from an initiator station. Then, each responder station can send training signals to the initiator station in a set of ordered phases associated with each responder station. The MSBRP eliminates inefficiencies associated with conducting multiple BRPs that include only pairs of stations.
Abstract:
An exemplary aspect is directed toward methods, apparatus, and systems related to spatial reuse with overlapping basic service set. A device may determine an overlapping basic service set (OBSS) associated with one or more access points. The device may then reduce a transmit power by a first margin. The device may then increase a packet detection threshold associated with the OBSS by a second margin. The device then sends an uplink data frame to at least one of the one or more access points.

This disclosure describes systems, methods, and devices related to deterministic backoffs and collision avoidance. A device may identify a first transmission received from a first device, wherein the first transmission is over a shared access medium. The device may identify a second transmission received from the first device, wherein the second transmission is over the shared access medium. The device may determine an available transmission slot between the first transmission and the second transmission. The device may transmit, during the available transmission slot, a third transmission.
Abstract:
A device is disclosed that may identify a frame received from an access point. The device may cause to buffer the payload field. The device may determine that a first payload, in a first payload field, corresponds to a multiband link aggregation (MBLA) Ethertype based at least in part on a logical link layer controller (LLC) field and a subnetwork access protocol (SNAP) Ethertype MBLA field in the first payload, wherein the first payload is within the payload field. The device may cause to remove a LLC MBLA header field from the first payload field. The device may cause to buffer a packet in a reordering queue, wherein the packet is in a second payload field that is in the first payload field. The device may order the packet among a plurality of packets in the reordering queue.
Abstract:
In dense environments, OBSSs can still be very close to each other. Spatial reuse attempts to tune sensitivity levels and transmit power in devices to isolate as much as possible the different OBSSs, so that OBSSs do not share the medium in time, but rather reuse the medium, which is a great addition from IEEE 802.11ax. Interference can however still happen, especially at the edge of BSSs where, for example, there are hidden node(s). Spatial reuse might even increase this interference in this scenario. Instead of forcing protection with RTS/CTS every time on the edge of BSSs, which can have a negative impact on the spatial reuse and on area throughput, inter-BSS interference avoidance solutions can be applied.
Abstract:
Some embodiments relate to a wireless network communications using Wireless Local Area Networks (WLAN). Some embodiments relate to high-efficiency wireless local-area networks (HEWs). Some embodiments relate to IEEE 802.11ax (and/or IEEE 802.11ac or IEEE 802.11ax+). Some embodiments relate to methods and devices for spatial reuse in any of these communications environments. Some embodiments relate to conditional reuse for Other Basic Service Set (OBSS) master stations and/or stations. Some embodiments relate to conditions that enable a HEW device to spatially reuse a portion of the wireless medium when the HEW device accurately determines a tolerable interference and either transmits an indication of the tolerable interference and/or lowers its own transmit power in accordance with the accurately determined tolerable or acceptable interference.

The device may cause to send the second A-MPDU subframe to the station device using a multi-band transmission on the first channel and the second channel.
Abstract:
Simultaneous dual band operation (2.4 and 5 GHz) is common in APs on the market today, and tri-band devices are expected in the market soon. Link aggregation can also be applicable to multiple air interfaces in the same band (for instance 2 independent IEEE 802.11ac/ax air interfaces at 5 GHz on 2 different 80MHz channels). One exemplary aspect provides technology that enables significantly higher throughput and/or higher reliability for two stations (STAs) or a STA and the access point (AP) when the devices support simultaneous multi-band operation.
